"Without passion man is a mere latent force and possibility, like the flint which awaits the shock of the iron before it can give forth its spark"

This quote by Henri Frederic Amiel talks to the value of passion in life. Without interest, a person is like a flint, which is a sort of stone that can create stimulates when struck with iron. The flint is a concealed force, indicating it has the prospective to develop stimulates, but it needs the shock of the iron to in fact do so. Similarly, without interest, a person has the prospective to do fantastic things, however they require the spark of enthusiasm to in fact bring that prospective to life. Enthusiasm is the driving force that can turn potential right into fact. It is the spark that can fire up a person's aspiration as well as help them to accomplish their goals. Without passion, a person resembles the flint, waiting on the shock of the iron to highlight their true capacity.
